The anomalous Floquet Anderson insulator in a continuously driven optical lattice
Arijit Dutta, Efe Sen, Jun-Hui Zheng +2
The anomalous Floquet Anderson insulator (AFAI) has been theoretically predicted in step-wise periodically driven models, but its stability under more general driving protocols has…
Local readout and control of current and kinetic energy operators in optical lattices
Alexander Impertro, Simon Karch, Julian F. Wienand +4
Quantum gas microscopes have revolutionized quantum simulations with ultracold atoms, allowing to measure local observables and snapshots of quantum states. However, measurements s…
Cold-atom quantum simulators of gauge theories
Jad C. Halimeh, Monika Aidelsburger, Fabian Grusdt +2
Gauge theories represent a fundamental framework underlying modern physics, constituting the basis of the Standard Model and also providing useful descriptions of various phenomena…
Floquet topological phase transitions induced by uncorrelated or correlated disorder
Jun-Hui Zheng, Arijit Dutta, Monika Aidelsburger +1
The impact of weak disorder and its spatial correlation on the topology of a Floquet system is not well understood so far. In this study, we investigate a model closely related to…
Frustrated extended Bose-Hubbard model and deconfined quantum critical points with optical lattices at the anti-magic wavelength
Niccolò Baldelli, Cesar R. Cabrera, Sergi Julià-Farré +2
The study of geometrically frustrated many-body quantum systems is of central importance to uncover novel quantum mechanical effects. We design a scheme where ultracold bosons trap…
Superconductivity in a Topological Lattice Model with Strong Repulsion
Rahul Sahay, Stefan Divic, Daniel E. Parker +8
The highly tunable nature of synthetic quantum materials -- both in the solid-state and cold atom contexts -- invites examining which microscopic ingredients aid in the realization…
The cold-atom elevator: From edge-state injection to the preparation of fractional Chern insulators
Botao Wang, Monika Aidelsburger, Jean Dalibard +2
Optical box traps for cold atoms offer new possibilities for quantum-gas experiments. Building on their exquisite spatial and temporal control, we propose to engineer system-reserv…
Emergence of fluctuating hydrodynamics in chaotic quantum systems
Julian F. Wienand, Simon Karch, Alexander Impertro +6
A fundamental principle of chaotic quantum dynamics is that local subsystems eventually approach a thermal equilibrium state. Large subsystems thermalize slower: their approach to…
State-dependent potentials for the and clock states of neutral ytterbium atoms
Tim O. Höhn, Etienne Staub, Guillaume Brochier +2
We present measurements of three distinctive state-(in)dependent wavelengths for the clock transition in atoms. Specifically, we d…
Real-space detection and manipulation of topological edge modes with ultracold atoms
Christoph Braun, Raphaël Saint-Jalm, Alexander Hesse +3
Conventional topological insulators exhibit exotic gapless edge or surface states, as a result of non-trivial bulk topological properties. In periodically-driven systems the bulk-b…
Preparing and Analyzing Solitons in the sine-Gordon Model with Quantum Gas Microscopes
Elisabeth Wybo, Alvise Bastianello, Monika Aidelsburger +2
The sine-Gordon model emerges as a low-energy theory in a plethora of quantum many-body systems. Here, we theoretically investigate tunnel-coupled Bose-Hubbard chains with strong r…

Federica Maria Surace, Pierre Fromholz, Nelson Darkwah Oppong +2
We introduce a method for quantum simulation of U lattice gauge theories coupled to matter, utilizing alkaline-earth(-like) atoms in state-dependent optical lattices. The prop…
